Answer

Width = $4.06$ m. Length= $4.45$ m.

Work Step by Step

Let the width be x meters. Then the length is $(x+0.39)$ meters. Double the sum of the sides equals the perimeter: $2[x+(x+0.39)]=17.02$ $2(2x+0.39)=17.02$ $4x+0.78==17.02$ $4x=16.24$ $x=4.06$ Width = $4.06$ m. Length=$4.06+0.39=4.45$ m
